alt Hacker NewsPut yourself in the shoes of the police here:
A store keeper emails this shield group and says "hey this person came into my store and engaged in disruptive behavior."
An Amazon security personnel emails this shield group and says "hey this person came into our office and engaged in disruptive behavior."
What makes one of these so much more impactful than the other?
I'm saying that the alternative is "An Amazon security personnel or store keeper reports a crime via the normal public channels and there's the usual paper trail for it". Your premise that this is only ever used for anything benign is what I'm disagreeing with here; obviously if you assume it, then nothing sketchy is going on, but at that point the argument is circular.
